Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

High‐Brightness Delayed Imaging Realized by Embedding Zinc Gallate Nanocrystals Into Glass
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT X‐ray delayed imaging technology leverages an “irradiation‐storage‐thermally stimulated readout” mode, demonstrating unique advantages in intermittent monitoring scenarios such as high‐temperature/high‐radiation environments. This typically requires materials combining abundant carrier‐trapping energy levels with structural thermostability ...

He jishu有机-无机杂化钙钛矿晶圆在大面积X射线探测方面显示出巨大的潜力，尤其是自供电钙钛矿X射线探测器由于具有低功耗、便携性和适应性强等优点也受到越来越多的关注。然而，目前的钙钛矿晶圆在光学透明度上的差异表明钙钛矿晶片的晶体质量较差，这限制了X射线探测器的性能和稳定性。针对以上问题，提出基于能带工程的钙钛矿异质结自供电探测新策略，通过热压诱导结晶，开发出梯度温控双向压制工艺，成功制备出具有清晰界面的MAPbBr3/MAPbCl3异质结晶圆。测试结果表明，Au-MAPbBr3/MAPbCl3 ...

Preparation and Characterization of FeOx/Rh(111) and CoOx/Rh(111) Model Catalysts [PDF]
, 2014 多相催化剂的表面是催化反应的活性位点，表面组成、粒径和结构决定了催化剂的催化性能。真实催化剂结构复杂并且表面不均一，阻碍了表面灵敏的表征手段的运用，无法精准确定其构效关系。构建成分简单结构单一的模型催化剂表面可简化传统催化剂的复杂性，用以研究气体吸脱附、催化活性和选择性、构效关系等催化问题。本论文在超高真空环境中制备模型表面FeOx/Rh(111)和CoOx/Rh(111)，应用表面科学仪器X-射线光电子能谱(XPS)和低能离子散射谱(LEIS)对模型表面进行表征，取得了如下结果： 一、在高温 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Precise control of chemical ordering in bimetallic nanocatalysts offers a route to decouple activity and selectivity in acetylene hydrogenation, but direct atomic‐scale evidence linking surface order to catalytic performance is scarce. Here, we tune Pd‐Cu nanoalloys from chemically disordered to highly ordered states by composition control and
